BRiCK-KILN.

SPECIFICATION forming part of Letters Patent No. 259,519, dated June 13, 1882.

Application led January 3, 1882. (No model.) l

1o the entire interior ofthe kiln rendered avail-v able for the piling ot' bricks.

In the accompanying drawings, Figure 1 is a longitudinal section of a brick -kiln constructed in accordance with my invention 5 Fig. 2, a sectional plan of the same on the line l 2; Fig. 3, a transverse section on theline 3 4; Fig. 4, Sheet 2, a diagram showing the arrangement of outlet-lines and dampers of a series of three kilns, and Fig. 5 a diagram illustrating anzo other feature of the invention.

The kiln is of rectangular form, and has side walls, A, end walls, A, and arched top A2.

B are the furnaces, which are arranged in rows along the outside ofthe walls A, and communicate with the /chamber D of the kiln through dues ct, each consisting of' an internal recess or depression formed in said walls A.

Centrally in the door E of the kiln is formed a row of openings, b, which communicate with 3o a ue, F, beneath said floor, this fine communicating at each end with a transverse ue, H. Two dampers or valves, d, are used in connection with the tlues F and H, one valve being arranged at each end of the iiue F, as shown in the diagram, Fig. 4. On each side of the kiln is a sunken iiue, G, which communicates with the chamber D of the kiln through openings e at the base of the side walls, each of these openings being furnished with a valve, 4o f, having a rod whereby it can be operated from the outside of the kiln. Each of the side ilues, G, communicates with the end flues, H, a damper, g, being arranged at each end of each ot' the dues G. (See Fig. 4.) A chimney or 4 5 stack, K, provides for the maintenance of draft through the dues F, G, and H, the dampers Z and g providing for the general regulation of the draft-that is to say, permitting a direct or indirect flow ot' the products of combustion through any of the dues, or providing for the cutting ott' of the drat't entirely from any of said lines; but in order to provide for a more accurate regulation of the draft than this affords I use the valves f, whereby the draft may be contined to any part ot' either of the dues G, and the products ot' combustion thus directed to any part of the kiln, as the proper burning of the contents of said kiln may demand, so that even burning is insured, and a product of uniform excellence obtained.

Access to the chamber D is obtained through doors J in the side walls, A, and the interior of the chamber D is entirely unobstructed by fire-place or due casings, so that the piling ot' the bricks is not interfered with or the capacity ofthe kiln diminished. The rectangular shape of the kiln permits the piling of the bricks throughout the entire chamber D, there being no waste space as in a circular kiln.

In the center of the arched roof A2 of the kiln is an opening which, when the kiln is at work, is closed by a cover, m, but when the contents of the kiln have been properly burned the cover is removed and one end of a pipe, n, applied to the opening, the other end of the pipe communicating with the chamber D of another kiln, as shown in Fig. 5. The hot.v

gases from the interior of the first kiln are thus directed to the second kiln and serve to dry or partially burn the contents of said second kiln.

I claim as my invention A 1. The combination of the kiln having the central chamber,D,with the eXternalire-places, B, communicating with said chamberD through tlues a, each consisting of a simple recess or depression in the inside of the wall of the kiln, as set forth. Y

2. The combination of the kiln having the central chamber, D, fire-places communicating therewith, and exit-dues G G, located at the opposite sides of the kiln, and communicating with the chamberD near the bottom, through independently-valved openings e, as set forth.

3. The combination of the kiln having the chamber D, the dre-places B, the dues a, the

central discharge-Hue, F, with openings Z1, and the side exit-fines, G, with their independentlyvalved openings e, as set forth.

4. The combination of the kiln having ire- 5 places B and chamber D,1;he central outletiue, F, side outlet-hues, G G, end connecting ues, H, and valves or dampers d and g, as I specified. l

In testimony whereof I have signed my name to this specification in the presence of' two sub- 1o soribing Witnesses.

ANDREW H. FORBES.
